    "abstract": "We introduce the entanglement gauge describing the combined effects of local\noperations and nonlocal unitary transformations on bipartite quantum systems.\nThe entanglement gauge exploits the invariance of nonlocal properties for\nbipartite systems under local (gauge) transformations. This new formalism\nyields observable effects arising from the gauge geometry of the bipartite\nsystem. In particular, we propose a non-Abelian gauge theory realized via two\nseparated spatial modes of the quantized electromagnetic field manipulated by\nlinear optics. In this linear optical realization, a bi-partite state of two\nseparated spatial modes can acquire a non-Abelian geometric phase.",
